Solve the quadratic equation by using either a numeric or a graphic approach.

x^2-11x-121 = 0

x = 11/2 + 11/2√5 or x = 11/2 + - 11/2√5

Step-by-step explanation:

For this equation: a=1, b=-11, c=-121

1x^2-11x-121=0

Step 1: Use quadratic formula with a=1, b = - 11, c = - 121.

x = (-b±√b^2-4ac) / 2a

x = ( - (-11) ±√ (-11) 2-4 (1) (-121)) / 2 (1)

x = (11±√605) / 2

x=11/2 + 11/2√5 or x=11/2 - 11/2√5

I recommend using a site called MathPapa for problems like this.
